Inspect Image for Defects

[areen_jj]

Hello 

I have images for car parts and need to check each part for fractions Just like the images attached 

I tried to use the golden template but it will not work if the image moved even a bit.

then i tried the  map defect but may some part be thinner or thicker 

so 

any ideas please 🙂

Hello areen_jj,

The golden template might be the algorithm for you but you need to set some thresholds so you don't have such precision. This also has to do with the orientation of the image and for that, it's important to set a coordinate reference such as you can align the algorithm. 

I found this video which I think will give you a base that you can use for your test. This piece has some easily definable shapes that you can use to detect the orientation and make the alignment. Remember also that the illumination is important and will have differences if you have pictures with different intensities.
